The Problem We Solve
Australia has a quiet housing crisis among its most vulnerable citizens. Age Pensioners — people who have worked and contributed their entire lives — are spending 60–70% of their pension on rent alone, leaving almost nothing for food, healthcare, or dignity. Social isolation among seniors costs the Australian economy $2.7 billion per year in healthcare and social services — equivalent to smoking 15 cigarettes a day in health impact.
The HSS Solution — Group Co-Tenancy
House Sharing Seniors operates a professionally managed Group Co-Tenancy model — curated, vetted, compatible groups of seniors sharing premium properties. This is fundamentally different from traditional spare-room or boarding models. Each member signs an individual lease. Each qualifies independently for Government Rent Assistance (CRA). The result is dramatic.
Social Return on Investment (SROI)
Against a $125,000 pilot investment, HSS generates extraordinary social value — and unlike most social programs, the benefit compounds every year at zero additional cost. Once a member is placed in an HSS Group Co-Tenancy, the $15,410/year social saving continues indefinitely. The initial investment is made once. The return never stops.
Most social programs require ongoing funding to sustain their impact. HSS does not. The $125,000 investment establishes the platform and first cohort. From that point, every year of continued tenancy generates the same $15,410 per member in social value at no further cost to the funder. Year 2 onwards is pure compounding return on the original investment.
Per Member Annual Social Value — 2% Aged-Care Delay Scenario
| Benefit Component | Per Member / Year | Recurs? |
|---|---|---|
| Direct rent saving + CRA ($300/wk × 52) | $15,600 | ✓ Every year |
| Social isolation cost avoidance | $1,565 | ✓ Every year |
| Healthcare reduction (44% fewer GP visits) | $540 | ✓ Every year |
| Aged care delay — 2% scenario ($1.5M ÷ 1,500) | $1,000 | ✓ Every year |
| Total — 2% aged-care delay scenario | ≈$18,700 | Every year at $0 added cost |
SROI by Scenario — Year 1 (against $125K investment, 1,500 members)
| Scenario | Per Member/yr | Total/yr | SROI Year 1 |
|---|---|---|---|
| Floor — direct rent + CRA saving only | $15,600 | $23.4M | $187:1 |
| 2% aged-care delay — adds isolation, healthcare + 2% aged-care avoidance | ≈$18,700 | $28.1M | $225:1 |
| 5% aged-care delay — aged-care component rises to $2,500/member | ≈$20,200 | $30.3M | $242:1 |
Year 1 figures against $125K one-time investment, 1,500 members. Floor = direct rent+CRA saving only ($300/wk × 52). Upper scenarios add social isolation avoidance ($1,565/member), healthcare reduction (44% fewer GP visits, $540/member), and aged-care delay at 2% and 5% of cohort respectively. Multi-year SROI (NPV at 5%): 3-year ~$529:1, 5-year ~$841:1. Against original sunk development costs: $619:1. Full methodology available on request.
